Determine the time when the velocity of the particle is zero

WebThe velocity curve also tells us whether the car is speeding up. In our earlier example, we stated that the velocity was constant. So, the car is not speeding up. Graphically, you can see that the slope of these two lines is 0. This slope tells us that the car is not speeding up, or accelerating. WebFor example, a person standing up from a chair or a plane taking off from a runway. In these cases, there is a clear change from zero velocity to non-zero velocity even though the object starts out at rest. This implies that there must be a moment where the object's acceleration is non-zero although the object remains in the same position. WebIf you’re not changing your speed and you’re not changing your direction, then you simply cannot be accelerating—no matter how fast you’re going.

An object which moves in the negative direction has a negative velocity. If the object is slowing down then its acceleration vector is directed in the opposite direction as its motion (in this case, a positive acceleration). Is there negative speed?
